Technology Features

Full HD Uncompressed Video
Uncompressed video
Uncompressed video is digital video information that has not been compressed, or was not processed with compression on it when the video was captured directly from a camera. It has variable data transfer rates...



HDBaseT delivers uncompressed HD video to a network of devices or as a point-to-point connection. Uncompressed content supports all video sources, including legacy products, accurately renders gaming graphics and features such as Electronic program guides, and does not degrade video quality or add latency.

HDBaseT supports TV and PC video formats including standard, enhanced, high-definition and 3D video.

Audio

Audio is a requirement for most consumer electronics (CE) devices. Audio is passed through the same media as video, so all standard formats are included.

100BaseT Ethernet

HDBaseT provides Internet capability, enabling televisions, stereos, computers and other CE devices to communicate with each other and access multimedia content, including video, pictures and music stored around the house.

Power over Cable

Sending power over the same Cat5e/Cat6 cable gives people the option to forgo plugging devices into the wall for power, allowing greater mobility. HDBaseT uses existing Power over Ethernet

 (PoE) technology and the next generation PoE+ to source low consuming CE devices, such as low-power Blu-ray players, monitors and TVs, and eliminate the need for external power cables. HDBaseT can power remote TVs and other devices up to 100 watts. A 40” TV connected via an HDBaseT enabled Cat5e/6 cable requires no power source, as it can be powered with 70 watts.

Various Control Signals

HDBaseT delivers different types of control signals with different purposes, starting from CEC that operates basic functionality such as power-on, power-off and play/stop, to RS232/USB and IR that operate remote equipment even when it is located in a different room.
